| Abstract | Nanorod structured Si1_xGex anodes have been prepared by depositing Si1_xGex coatings onto the electrodeposited Ni nanocone arrays for high capacity Li-ion batteries. The obtained samples were characterized by field emission scanning electron microscopy. The electrochemical performance was evaluated by a galvanostatic battery testing. It is found that Si1_xGex nanorod displays obvious improved electrochemical performance compared to the pristine film anode. The increase of the Ge content for the Si1_xGex anode can improve the capacity retention greatly while retain a rather high capacity. For Si0.71Ge0.29 anode, the charge capacity remains 841mAh/g after 101 cycles, surpassing the Si anode of 662 mAh/g. |
